Emek and Luna reached a wide river just as the sun began to sink. A bridge of stepping stones stretched across the water, but several stones were missing their number cards. The visible stones were labeled 2.35, 2.40, 2.45, and 2.50. Nearby, they found the cards 2.30, 2.55, and 2.60. By reading each decimal correctly and placing the missing cards so the numbers increased in order, they completed the bridge. Following the safe decimal path, they crossed the river and reached the opposite shore before sunset.

Hint
Look for the smallest decimal.
Which number card should be placed before 2.35 to keep the bridge numbers in increasing order?

Check which decimal is the smallest.
Next🎉 Congrats! You got this question!
Hint
Count the jumps between consecutive numbers.
The completed bridge has the numbers 2.30, 2.35, 2.40, 2.45, 2.50, 2.55, and 2.60. If each step increases by 0.05, how many equal increases are there from 2.30 to 2.60?
Correct! There are 6 equal increases of 0.05.
Count the spaces between the seven numbers, not the numbers themselves.
